Three new species of Brauer, 1870 (Trichoptera, Xiphocentronidae) from Mexico.

Three new species of the genus (Trichoptera, Xiphocentronidae) are described from Nearctic and Neotropical regions of Mexico. Xiphocentron (Glyphocentron) flinti sp. nov.

Does size matter? An analysis of the niche width and vulnerability to climate change of fourteen species of the genus from North America.

The niche comprises the set of abiotic and biotic environmental conditions in which a species can live. Consequently, those species that present broader niches are expected to be more tolerant to changes in climatic variations than those species that present reduced niches. In this study, we estimate the amplitude of the climatic niche of fourteen species of rattlesnakes of the genus to evaluate whether those species that present broader niches are less susceptible to the loss of climatically suitable zones due to the projected climate change for the time period 2021-2040.

Dispersal and resistance to starvation in Raoiella indica (Acari: Tenuipalpidae).

Raoiella indica Hirst (Tenuipalpidae) is an obligate phytophagous mite that has rapidly colonized wide areas of tropical America and causes severe injuries, mainly to plants in the families Arecaceae, Heliconiaceae, Zingiberaceae and Musaceae. This study evaluates biological attributes of the species that could explain its potential as invasive pest, its capacity to survive when deprived of food and its dispersal mechanisms, including passive displacement by wind and possible phoretic association with insects. This mite has a higher resistance to starvation than other phytophagous mites, with a maximum 12 days for adult females.

The impact of global warming on the range distribution of different climatic groups of Aspidoscelis costata costata.

The ectothermic nature of reptiles makes them especially sensitive to global warming. Although climate change and its implications are a frequent topic of detailed studies, most of these studies are carried out without making a distinction between populations. Here we present the first study of an Aspidoscelis species that evaluates the effects of global warming on its distribution using ecological niche modeling.
